Tube 800/40-26.5 TR218A
Product.Nr.: 990017404
Manufacturer: Novio
This high-quality tube in size 800/40-26.5 is designed for use in heavy industrial and agricultural applications. It is ideal for high-volume tyres where high load capacities and reliable air pressure are required. Thanks to its robust construction and the proven TR218A valve, the tube offers a durable and low-maintenance solution for machines and trailers in professional use.
Technical data
- Tube size: 800/40-26.5
- Inch size: 26.5 inch
- also suitable for: 800/45-26.5
- Valve type: TR218A
Valve-specific data (TR218A)
- Valve design: Straight, high-volume tube valve for agricultural and industrial tyres
- Typical rim hole diameter: approx. 20.5 mm (0.805") for large bore in the rim
- Valve length above rim surface: approx. 38–45 mm (depending on version)
- Valve core: Replaceable insert, allows easy deflation and refilling
- Suitable operating pressures: Designed for medium to high operating pressures in large tyres
- Design advantage: Large cross-section opening for fast air flow during inflation and deflation, robust metal construction for high loads
Benefits and application range
This tube is specially designed for large-dimension tyres in size 800/40-26.5 and can additionally be used in tyres of size 800/45-26.5. It is therefore particularly suitable for:
- Agricultural trailers and slurry tankers
- Forestry and municipal machinery
- Industrial transport equipment with high-volume tyres
The tube impresses with its robust construction, which ensures stable pressure retention even under demanding conditions. The TR218A valve enables fast and convenient inflation and deflation, reducing downtime and simplifying maintenance. Thanks to its suitability for several similar tyre sizes, this tube offers a flexible and economical solution for professional users who depend on reliable tube systems.
Frequently asked questions about this product
The valve designation describes two things: the stem diameter — which must fit the hole in the rim — and the shape, i.e. straight or angled.
Only the bore matters for a proper fit: a valve fits perfectly only if its stem matches the bore in the rim. Whether it is straight or angled makes no difference — that is a question of accessibility.
An overview of the types:
| Type | Shape | Bore | typically used for |
|---|---|---|---|
| TR13 | straight, rubber | 11.5 mm | Car and trailer wheels |
| TR4 / TR6 | straight, short | 11.5 mm | Small wheels, garden tools |
| TR15 | straight, rubber | 16 mm | Agricultural machinery, tractor rims |
| TR87 | 90° angled | 11.5 mm | Small wheels, solid rims |
| JS8 (DIN 7777) | 90° angled, same as TR87 | 11.5 mm | small wheels, solid rims |
| JS2 | Approx. 70° angled | 11.5 mm | Industrial and small wheels |
| V3-02-7 (TR75) | 100° single-bend metal angle valve with screw-on base | 12.2 mm | Commercial vehicles, lorries, trailers, agricultural and industrial machinery such as forklift trucks |
| V3-06-3 | Triple-bend brass truck screw-on valve (90°/139°/139°) | 9.7 mm | 20-inch truck and trailer tubes (6.00-20 to 9.00-20), also 22.5-inch tube-type tyres |
| TR218A | Straight metal air-water valve, two-piece | 15.9–16 mm | High-volume tubular tyres for agricultural and industrial use, tractors |
V3-02-7 in detail: Also known as ETRTO V3.02.7 and US designation TR75. Dimensions: Horizontal leg length 22.5 mm, vertical leg length 71.5 mm, total height approx. 91 mm. The valve base is screwed on, not pressed in — this makes it significantly more robust than a rubber valve.
V3-06-3 in detail: Also known as ETRTO V3.06.3. Triple-bend brass screw-on truck valve: the first bend is 90°, the other two 139° each — this guides the filling end past the rim flange and keeps it accessible even with twin tyres and deep rim wells. Leg dimensions approx. 20.5 / 46 / 20.5 / 47.5 mm (approx. 135 mm developed length), rim hole 9.7 mm. The valve is fastened to the tube with a sealing washer and nut instead of being vulcanised in. In our range on the 20-inch tubes 6.00/6.50-20, 7.00/7.50-20, 8.25-20 and 9.00-20.
TR218A in detail — the valve for water ballast: What makes this type special is the option for liquid ballasting: the hose is partially filled with water to increase the vehicle’s weight and thus improve traction — a common practice with tractors.
- Design: straight, robust metal valve, usually in two parts. Unscrewing the inner CH3 valve insert creates an extra-large opening — allowing for quick filling with air or liquid.
- Rim bore: 15.9 to 16 mm (0.625 inches).
- Length: typically around 38 to 48 mm total height above the rim.
- Mounting: a rubber base approximately 80 mm in diameter for vulcanising onto the inner tube, plus a lock nut for secure attachment to the rim.
Reducing sleeves: A TR15 valve does not fit into an 11.5 mm bore. Conversely, there are sleeves that allow a TR13 valve to fit into a 16 mm bore.
Whether straight or angled is not a question of fit, but of accessibility: with closed rims or small wheels, it is often impossible to reach the valve with a pump using a straight valve — in which case an angled one is used.
Not sure which valve is fitted? A photo of the old valve is all we need to identify it. Choose from: inner tubes, bead tapes and valves.
